WILLIAM F. WOLFSBERGER, OF ST. LOUIS, MISSOURI.

CORD STRETCHER.

Application filed October 1, 1923.

To all whom it may concern:

Be it known that I, WILLIAM F. WOLFS- BERGER, a citizen of the United States, residing at St. Louis, State of Missouri, have in vented certain new and useful Improvements in Cord Stretchers, of which the following is a specification.

This invention relates to devices for stretching cords and the like, and has for one of its objects to provide a simply constructed device of this character whereby sections of the cord may be conveniently stretched to prevent them from further stretching when in use.

The improved device is designed for stretching the cords which are to be employed for stringing beads and the like, so that the cords will not be further stretched when the strings of beads are worn about the neck.

lVith this and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative. of the preferred embodiment of the invention- 7 Figure 1 is a perspective view of the improved device.

Figure 2 is a transverse section, enlarged on the line 2-2 of Figure 1.

The improved device includes a base or platform 10 preferably mounted on supporting legs 11, and with a longitudinally directed channel or guideway 12 having overhanging edges 13.

Extending upwardly from the base 10 are coacting standards 14 each having a laterally directed lower end 15 bearing on the bottom of the guideway 12 and beneath the overhanging edges 13. By this means the standards are movable within the guideway toward and away from each other but cannot be removed upwardly therefrom. Each of the standards is provided with means, such as eyes 16, for attaching the cord to be stretched and represented at 17.

Hinged at 18 to the confronting faces of the standards are braces 19, the free ends of the braces being chisel pointed to frictionally engage the bottom of the guideway and thus hold the standards from movement to- Serial No. 666.048.

ward each other, and also hold the cord in stretched condition.

The cords referred to are those employed for stringing beads and like purposes and are generally stretched and coated with wax or the like to retain them in stretched condition, so that after the beads are disposed thereon, the cords will not be further stretched and spaces develop between the in dividual beads.

In operating the improved device one or both of the braces 19 is released and the cord 17 attached at its ends to the eyes 16. The standards are then moved manually away from each other to apply the requisite strain to the cord and the strained condition retained by adjusting the braces 19 as before described. A wax or waxen compound is applied to the cord either before or after stretching, to prevent the cord from' relax ing after removal from the standards.

The improved device is simple in construction and can be made of any required size or material.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is 1. A device of the class described comprising a base having a longitudinal channel closed at the bottom and with overhanging sides, coacting standards movably bearing upon the closed bottom of the channel and each provided with forwardly and rearwardly directed foot portions bearing upon the closed bottom of the channel and extending laterally beneath the overhanging sides of the channel, and a member to be strained attached to the standards near their upper ends, whereby the, forcing of the standards away from each other will cause the lateral feet to bind in the channel and lock the standards in adjusted position.

2. A device of the class described comprising a base having a longitudinal channel closed at the bottom and with overhanging s'ides coacting standards movably bearing upon the closed bottom of the channel and each provided with forwardly and rearwardly directed foot portions bearing upon the closed bottom of the channel and extend ing laterally beneath the overhanging sides of the channel, brace elements swingingly attached at their upper ends to the confronting faces of the standards and chisel pointed at their lower end and grippingly engaging the 10 bottom of the channel.

' In testimony whereof, I aflix hereto.

lVILLIAM F. WOLFSBERGER.
